Re: internally trimming characters

Is there an easy way to remove characters belong to a set (like numbers) from anywhere in a string? stringByTrimmingCharacters only works on the ends of the string.


This is the easiest way I know of, personally...

NSCharacterSet *digits = [NSCharacterSet decimalDigitCharacterSet];
NSMutableString *originalWord = [NSMutableString stringWithString:@"F1o2o3b4a5r"];
NSRange r = [originalWord rangeOfCharacterFromSet:digits];
while (r.location != NSNotFound) {
[originalWord deleteCharactersInRange:r];
r = [originalWord rangeOfCharacterFromSet:digits];
}
